IMPROVEMENT IN CARRIAGE AND WAGON BRAKES.

Specification forming part of Letters Patent No. 155,1 16, datedSeptember 15, 1874; application filed August 8, 1874.

To all whom it may concern Be it known that I, W. H. H. SNELLBA- KER, ofSt. Louis, State of Missouri, have invented an Improvement inVehicle-Brakes, of which the following is a specification:

The object of my invention is to construct a simple, effective, andportable vehicle-brake, which can be applied to all kinds of wagons orbuggies; and consists of a brake-lever which is constructed so as toallow a semicircular ratchet to pass through it, and which carries apawl that can be made to engage with the teeth of the ratchet bypressing the end of the brake-lever to operate the brakerod, havingformed upon it enlarged ends, constructed in such a manner as to admitof the reception of a shoerod within such ends, and keyed to the same,and also the method of attachment of the shoe to the shoe-rod arms.

By reference to Figure 1 of the accompanying drawing, my invention willbe readily un' derstood.

B is the semicircular iron ratchet, which passes through a slot in thebrake-lever A.

a is a metallic cap, which crowns the end of the brake-lever, and hasits inner end resting upon a concealed rubber or helical spring. The rodK has at its lower extremity a pawl, c, which may be made to engage withthe teeth of the ratchet B when desired. V V is an iron brace,strengthened at the corners, to which the ratchet B is bolted. Thebrakehiver A is bolted to the brace above mentioned a c.

Fig. 2 is a vertical section of the brakelever, showing its internalconstruction and its connection with the brake-rod 0. d indicates theswell of the lever A, through which the ratchet B passes, and whichcontains the concealed pawl c.

Fig. 3 exhibits the construction of the brakebar P, which has acylinder, Gr, cast on each end, and is bolted to the vehicle throughbearin gs E. The cylinder G has formed within it a square mortise,adapted to receive one end of the shoe arm or rod, of correspondingshape,

as seen at 9, Fig. 5, which is firmly keyed thereto, the opposite end ofsaid shoe arm or rod being also formed square, as seen at f Fig. 5, uponwhich is adjusted the shoe H, which latter is held thereupon and securedthereto by the nut on the end of such shoe rod or arm, as seen in Fig.5. The enlargement of the ends of the brake-rod, by means of thecylinder G, causes the same to be operated more rapidly and easily whenapplying the brakes. The brake-shoe arm fis inserted in the cylinder G,and is secured to it by a key, .9, and is connected with the brake-rod Oby means of the stafi' I. H represents the brake-shoes, which can beremoved from the shoe-arm f, as more fully shown by Fig. 5.

Fig. 4 is a vertical section of the cylinder G, which shows that thebrake-arm f is united to the brake-bar F by means of the key 9.

The operation of my improved vehicle-brake will be readily understoodwhen it is stated that by pressing the metallic cap a of the brake-leverA, a spring concealed therein actuates a rod, K, which bears upon itslower end a pawl, e, and throws it in or out of gear with the teeth ofthe ratchet B. When the brake'lever A is about vertical the brakeshoes Hbear against the wheels of the vehicle by means of the brake-rod O,which is secured to the brake-bar F by the staff I. This brake-lever andthe bar are much stronger and simpler, and, being easier cast, are lessexpensive, while the pawl is securely protected from the weather, thebrake-bar being bolted to the bed of the vehicle, and the shoes maderemovable.

What I claim, and desire to secure by Let ters Patent, is

In a brake for vehicles, the combination of the brake-lever A, singleratchet B, and pawl 6 with the brake-bar F and removable shoearms f,-asshown and described.
